No one would deny that substitute teachers often have a tough time keeping students under control, but things got out of hand at Maxdale Elementary School in Killeen.

KWTX's Alex Cano reports that a substitute teacher was removed from a classroom after putting duct tape on the mouths of ten students. Killeen Independent School District spokesman Terry Abbott told KWTX three other students then complied with a demand they put duct tape over their own mouths as well.

Abbott said the students were evaluated by a school nurse after other teachers found out about the incident, and that the students involved were able to go about the rest of their school day.

The substitute teacher was immediately removed from the classroom and banned from KISD campuses. Child Protective Services has been notified, and KISD is cooperating with their investigation of the incident.
